ATP is produced
in the chloroplast by Chemiosmosis.
Chemiosmosis
requires a phospholipid bilayer, a proton pump, protons and ATPase.
Chemical Energy is used
to pump protons through a proton pump (intrinsic protein). This creates
a high concentration of protons (H+) inside the thylakoid disk.
ATP Synthase has a channel
that allows for the facilitated diffusion of protons back in through the membrane.
This activates ATP Synthase, which in turn catalyzes the formation of ATP.
In summary, the chemical energy
is transferred to a proton pump which creates a proton gradient across the membrane.
This gradient is used to activate the enzyme ATP Synthase. ATP Synthase
catalyzes the formation of ATP
